Match characters that are not inside certain HTML tag and does not contain a certain word

With these it helps A regular expression is the incorrect tool for this job. Even if it's just for a "quick fix", it's still not the correct tool.
The tool I like to use here is called XPath. Using PHP's DOMDocument and DOMXPath classes, we can find the value(s) you want.
code :
<?php
$html = <<<END
<p>This is one</p>
<p>This is one x x x</p>
<blockquote><i>something</i><p>This is one</p></blockquote>
END;

$DOM = new DOMDocument;
$DOM->loadHTML($html);
$xPath = new DOMXPath($DOM);

$p = $xPath->query('//p[not(contains(text(), "x x x")) and not(ancestor::blockquote)]');

foreach($p as $e){
    echo $e->nodeValue;
}

I hope this helps . I need to match all characters between the last occuring upper case word in a String and another word. Input Text:The CLEVER fox JUMPED OVER the big and (Hole 2) wall in the night. , This might not be the most effective solution, but it seems to work:
code :
String text = "The CLEVER fox JUMPED OVER the big wall in the night.";
String regex = "(\\b[A-Z]+\\s)(?!.*\\b[A-Z]+\\b)(.+?)(\\sin)";
Matcher m = Pattern.compile(regex).matcher(text);
if (m.find()) {
    System.out.println(m.group(2));
}

around this issue I'm not certain of your full question, but you'll need to use a Regex escaper for conditions like this one. The $ is a special character. It would be \$ to actually search for a dollar sign. You should look up other special characters and be aware of them too, though C# regex escaper will do the tick.
EDIT Like this:
code :
string[] names = 
{
    "Jordan Ghassari",
    "James Cunningham",
    "Ghabriel Bercholee",
    "O^Brian",
    "Depto #345",
    "This is Ex$ample",
    "$amuel"
};

string searchFor = Console.ReadLine(); // Input
searchFor = @"(?:(?<=^|\s)(?=\S|$)|(?<=^|\S)(?=\s|$))" + Regex.Escape(searchFor); // searchFor is input value to look for

Regex regEx = new Regex(searchFor, RegexOptions.IgnoreCase);

List<string> matchedNames = new List<string>();
foreach(string name in names){
    if (regEx.IsMatch(name))
    {
        matchedNames.Add(name);
    }
}

foreach (string match in matchedNames) 
{
    Console.WriteLine(match);
}

I wish this helpful for you I have a list of words with positive and negative sentiment e.g. ['happy', 'sad'] , I would build regular expressions dynamically turning a word:
code :
happy
h+a+p+p+y+
import re

re_list = [re.compile("".join(["{}+".format(c) for c in x])) for x in ['happy', 'glad']]
for w in ["haaappy","saad","glaad"]:
    print(w,any(re.match(x,w) for x in re_list))
haaappy True
saad False
glaad True

this one helps. Remove the ^ from it, that cause this. The caret mean basically "start the matching from the beginning of the line (token in your case)".

hope this fix your issue As pointed out in the comments a HTML parser is the ideal solution for your problem, however if you do for whatever reason want to use a regex, the following will work:
